Document Type and Number:
WIPO Patent Application WO/2023/123726
Kind Code:
A1
Abstract:
Disclosed is an anti-knocking and opening bottom-opening password padlock, comprising a lock body housing provided with lock ring holes which communicate with an inner cavity, a U-shaped lock ring, a password wheel set mounted on the lock body housing, a lock gate slidably mounted in the lock body housing, a control panel rotationally mounted in the lock body housing by means of a rotating shaft, and a control panel reset elastic piece for providing, for the control panel, an elastic holding force for keeping a contact control arm in close contact with an inner wheel of the password wheel set. Two ends of the lock ring, a side wall of which is provided with a clamping groove structure, can be inserted into the lock body housing via the lock ring holes, the lock gate can be inserted into the clamping groove structure of the lock ring, and the lock body housing is provided with a window for exposing a password identifier on the password wheel set. The control panel is located on two sides of the rotating shaft to respectively form an insertion stop arm that prevents disengagement from the clamping groove structure on the lock ring and a contact control arm which abuts against the eccentric outer circumferential surface of each inner wheel of the password wheel set. In the present invention, the stability of the control panel in the lock body is improved, and the potential risk of auto-unlocking when the lock body is shaken is avoided.
